MILLER, a citizen of theUnited States, and a resident of Newport, in the coun tyof Campbell and State 5 of Kentucky, have invented certain new and useful Improvements in TubeSupports for Sewing-Machines, of which the'foIIOWing is a specification. 4

. M'y invention relates to an improvement upon the box-loop'sewing-machine for-which Letters Patent No. 384,059, dated June 5, 1888, were granted Louis L. Miller, inventor, and

v.l rank Perkins, assignee. a

The object of my said formerdnvention was to provide eflicient mechanism for sewing in a box-loop.

The object of this invention is to provide an improved support for the tube-supporting bar. In the operation of the box-loop sewing- .20 machine of the classabove referred to the loop is sewed upon a horizontal pro ecting bar and the needle Working through or into the bar with the stitching along the top surface.

The objectof the present invention is to provide an efficient support underneath the To all whom it may concern: I

I Anotherobject of my invention is to provide a peculiar shaped roller which serves as a side guide for sewing box-loops overanglepieces, such as upon the check of a blinker of abridle.

In ordinary plain work the side guides, however, are not required, but are a very useful auxiliary in sewing loops on irregular-shaped pieces.

I have shown the supportfi as longitudinal and provided with four friction-rollers, as that is the best form of using it; but it is obvious that a single roller on the adjustable support would take off the spring of the bar as readily as the device herein shown, but would not be so satisfactory a feeding auxiliary. .So, also, the roller might be omitted in case of heavy work where the needle is suifi- This shape ciently strong to do the feeding, or where the loop is sufliciently large. toslip readily on the loop-supporting bar 4.

Having described my invention, what I claim isj 1. In a box-loop sewing-machine, the combination, with the tube-supporting arm 4, of the vertically-adjustable bracket or stand 6, and a series of rollers 14, journaled .in said bracket beneath the tube-supporting bar to facilitate the feed of the loop, substantially as described.

2. In a box-loop sewing-machine, the combination, with-(the tube-supporting .bar 4, of the adjustable bracket or stand 6, provided on its under side with a screw-threaded stud 7 and recesses 13, the frame provided with the boss 8, to engage said stud, and with the keeper-pin 10, to engage said recesses, and a series of rollers 14, journaled in saidabracket' beneath the supporting-bar, substantially as described.

3. In a boX loop-sewing-machine, the combination, with the tube-supporting bar 4, .of

the adjustable stand or bracket 6, provided with a series of rollers 14:, located beneath said bar, the adjustable side bracket 24, and the angle-supporting roller 30, journaled. said side bracket, substantially as described.

In testimony whereof I have hereunto set my hand.
